BP-Willow Bark Extract is an aqueous extract made from the freshly harvested bark of the Salicaceac and genus salix species of willow trees typically containing approximately 10% natural salicylates comprised of salicylic acid, salicin, salicortin, fragilin, populin, traiandrin, vimalin, tannins, beneficial flavonoids, and some minerals, acting synergistically as an analgesic on the skin and as a way to deliver naturally-derived salicylic acid.
